The Mikoyan-Gurevich MiG-23 is a variable-geometry fighter aircraft, designed by the Mikoyan-Gurevich design bureau in the Soviet Union. It is a third-generation jet fighter, the world's most-produced variable-geometry aircraft, along with similar Soviet fighters such as the Su-17 "Fitter". It was the first Soviet fighter to field a look-down/shoot-down radar and one of the first to be armed with beyond-visual-range missiles. Production started in 1969 and reached large numbers with over 5,000 aircraft built, making it the most produced variable-sweep wing aircraft in history. Today the MiG-23 remains in limited service with some export customers.
